  1. 21. Learning-Based Testing of Microservices : An Exploratory Case Study Using LBTest

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Peter Nycander; [2015]
    Nyckelord :microservices lbtest learning-based testing lbt trioptima;

    Sammanfattning : Learning-based testing (LBT) is a relatively new testing paradigm which automatically generates test cases for black-box testing of a system under test (SUT). LBT uses machine learning to model a SUT, and combines this with model-based testing. LÄS MER

  3. 22. Non-intrusive Patient Simulator for Medical Ventilator Software Verification

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Yuzhen Zhuo; [2014]
    Nyckelord :;

    Sammanfattning : Testing distributed real-time systems has been pervasively proven a challenging task within numerous industries. When the real-time nature of a system is combined with safety critical medical systems, having a reliable test system is of major importance. LÄS MER

  4. 23. Short-circuit Contributions from Fully-rated Converter Wind Turbines : Modeling and simulation of steady-state short-circuit contributions from FRC wind turbines in offshore wind power plants

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektriska energisystem

    Författare :Joakim Ahnlund; [2014]
    Nyckelord :;

    Sammanfattning : In recent years there has been an increase in wind power plants installed out at sea. The generated power of wind turbine generators (WTGs) are collected through numerous subsea cables into a single hub, the offshore platform. Subsequently, this platform is interconnected with the onshore main grid through a further stretch of cable. LÄS MER

  5. 24. Exploiting Redundancy and Asynchrony in Forward Exact Recoveries for Iterative Solvers

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Luc Jaulmes; [2014]
    Nyckelord :;

    Sammanfattning : This report presents a method to recover from faults detected by hardware in numerical iterative solvers. By exploiting redundancy inherent to an iterative solver instead of adding redundancy, we can interpolate lost data and thus devise an exact recovery scheme, which does not compromise mathematical convergence properties of the solver as methods based on restart would do.

  7. 25. Log-selection strategies in a real-time system

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Niklas Gillström; [2014]
    Nyckelord :Log-selection strategy; embedded real-time system; worst case execution time overrun; bit error; deadline miss; Fault injection;

    Sammanfattning : This thesis presents and evaluates how to select the data to be logged in an embedded realtime system so as to be able to give confidence that it is possible to perform an accurate identification of the fault(s) that caused any runtime errors. Several log-selection strategies were evaluated by injecting random faults into a simulated real-time system. LÄS MER
